Identification of Crop and Weed Seeds
Author: A.F. MusilPublisher: Scientific Publishers
ISBN: 9386237229
Category : Technology & Engineering
Languages : en
Pages : 221
Book Description
The book deals primarily for the identification of seeds of agricultural plants and field weeds. It is designed to serve as a guide for the identification of seeds in other related biological sciences in which a knowledge of the gross morphology of seeds is essential. Seed identification is a specialised field of botany that has been developed over the past 50 years to meet the problem of labeling agricultural and vegetable seeds. Special topics covered are Structural features, classification of grasses, Descriptions and keys to the genera and species. The book would prove very useful for researcher as well as agriculture students.
Manage Weeds on Your Farm

Book Description
Manage Weeds on Your Farm: A Guide to Ecological Strategies provides you with in-depth information about dozens of agricultural weeds found throughout the country and the best ways of managing them. In Part One, the book begins with a general discussion of weeds: their biology, behavior and the characteristics that influence how to best control their populations. It then describes the strengths and limitations of the most common cultural management practices, physical practices and cultivation tools. Part Two is a reference section that describes the identification, ecology and management of 63 of the most common and difficult-to-control weed species found in the United States.
Biology and Management of Problematic Crop Weed Species
Author: Bhagirath ChauhanPublisher: Elsevier
ISBN: 0128229357
Category : Science
Languages : en
Pages : 433
Book Description
Weeds are the main biological constraint to crop production throughout the year. Uncontrolled weeds could cause 100% yield loss. In Australia, the overall cost of weeds to Australian grain growers was estimated at AU$ 3.3 billion annually. In terms of yield losses, weeds amounted to 2.7 million tonnes of grains at a national level. In the USA, weeds cost US$ 33 billion in lost crop production annually. In India, these costs were estimated to be much higher (US$ 11 billion). These studies from different economies suggest that weeds cause substantial yield and economic loss. Biology and Management of Problematic Weed Species details the biology of key weed species, providing vital information on seed germination and production, as well as factors affecting weed growth. These species include Chenopodium album, Chloris truncata and C. virgate, Conyza bonariensis and C. canadensis, Cyperus rotundus, and many more. This information is crucial for researchers and growers to develop integrated weed management (IWM) strategies. Written by leading experts across the globe, this book is an essential read to plant biologists and ecologists, crop scientists, and students and researchers interested in weed science. - Provides detailed information on the biology of different key weed species - Covers weed seed germination and emergence - Presents the factors affecting weed growth and seed production

Color photos of over 700 weeds including seeds, seedlings, flowers, and mature plants. Appendix of non-native plants rarely or occasionally naturalized in California. Glossary of botanical terms. Bibliography of some of the most pertinent publications. Index to common names, scientific names, and synonyms. Each entry describes the plant category, family name, common name, and synonyms along with a summary of the important aspects of the plant’s life cycle, size, growth form, impact, method of introduction, and toxicity. You'll also find a description of the seedling, mature plant, roots and underground structures, flowers, fruits and seeds, spikelets and florets, spore-bearing structures, and post senescence characteristics for each entry. Also includes a description of the habitat where each is typically found and distribution in California, other states, and worldwide, along with maximum elevation at which the species is found. Rounding out each entry is a description of the methods of reproduction, seed dispersal, germination requirements and conditions, seed survival and longevity, early establishment characteristics and requirements, cultural practices and management options that have proven effective or ineffective in controlling infestations, and a notation of the species' inclusion on federal or state noxious weed lists.
The Triazine Herbicides

Languages : en
Pages : 604
Book Description
Over the past 50 years, triazines have made a great impact on agriculture and world hunger by assisting in the development of new farming methods, providing greater farming and land use capabilities, and increasing crop yields. Triazines are registered in over 80 countries and save billions of dollars a year. The Triazine Herbicides is the one book that presents a comprehensive view of the total science and agriculture of these chemicals. With emphasis on how the chemicals are studied and developed, reviewed, and used at the agricultural level this book provides valuable insight into the benefits of triazine herbicides for sustainable agriculture. - Presents previously unpublished information on the discovery, development and marketing of herbicides - Includes a vital section on the origin, use, economics and fate of triazine herbicides - Covers benefits of triazines in corn and sorghum, sugarcane, citrus, fruit and nut crops - Establishes best management practice and environmental benefits of use in conservation tillage
Identification of crop and weed seeds

Book Description
Cannabis products are the most widely trafficked drugs worldwide, and it also remains the most widely used drug worldwide. At the same time, production methods have become increasingly sophisticated, resulting in the availability in illicit markets of a wide range of cannabis products. This updated and significantly revised manual has been prepared taking into account both developments in analytical technology and advances in the science of cannabis. It is aimed at the harmonization and establishment of recommended methods of analysis for national drug analysis laboratories. The manual suggests approaches that may assist drug analysts in the selection of methods appropriate to the sample under examination and provide data suitable for the purpose at hand, leaving room also for adaptation to the level of sophistication of different laboratories and the various legal needs.
